Re: Question about QTR Print Tool and color

2012-11-27 by john

Thanks for posting this, Nick.  It is really useful for someone starting out with the printing tool.  I wonder if there is a way to put a cop in the files section here.

The link so to our internal wiki that we've set up for the students.  The wiki is basically a digital version of our instruction manual we give to students for all the various applications and hardware that they use including instructions on printing and profiling papers.

This change in luminance might be an adjustment for some photographers, but you should start to see closer output values in your shadows.  Using a too-bright monitor can result in dull and even nearly gray blacks.

I use ColorMunki to profile my papers, and it bypasses any Adobe/Apple/Photoshop configurations when generating the profile (I assume). Still, when I print from either PS or Lightroom, the prints look right on so long as I use the Colormunki-generated profile. When I tried Print Tool using the same profile, colors were way off.

Strongly suspect it's the "double profiling" problem or whatever it's officially called, where color management gets applied twice--once by Photoshop, again by printer. The prints come out extremely dark/muddy and colors way off.

I've tried various recipes but can't get a procedure that actually works. Probably missing a simple step; can't for life of me spot what it is. Much paper and time wasted so far,etc.
